11:20 a.m.
I'm trying to add Seam to an old EJB2 application so that we can do new development in
Seam and gradually port the old stuff into Seam.
I starting by merging the deployment directory of an "empty" Seam application,
SeamApp, (created with seam-gen new-project) into the exploaded deployment legacy
application, just to see if this was workable. There isn't really that much to copy
across:
- the jars, including SeamApp.jar.
- module entries in META-INF/application.xml.
- security.drl - the jboss rules' security defintions.
- Seam-specific entries in web.xml
- other files in SeamApp.war
I left META-INF/jboss-app.xml intact. It already contains a <loader-repository>
entry and cannot have two.
After this the old application worked fine and I could access home.seam.
Next I created a SFSB, DemoManager, using create-conversation in seam-gen and copied the
diff of the deploy the same way to the deploeyd old app. This time (also after server
restart) I get an exception when trying to access the new page:
